Using Binary Tree to Manage Revoked Certificates

NING Hong-zhou, LIU Yun, HE De-quan(School of Electronics and Information Engineering, Beijing Jiaotong University, Beijing 100044, China)  
In view of the complexity of certificate verification response and certificate verification in the 2-3 tree for managing revoked certificates, the binary tree is used to replace the 2-3 tree to manage the revoked certificates. It can simplify the structure of the tree and the attribute of the nods. By using the global number of the nods, locating and indexing of the nods become easy. And by using unique numbering of paths, processing of neighbourship verification is simplified greatly. Thus, the computing efficiency of certificate verification response of the server and certificate verification of the client is improved, and using the binary tree to manage revoked certificates becomes more practical.
